To all whom it may concern-" lie it: known that 1, DAVID Soo'rr Ar isoN,

a citizen of; the United States,' residing at Salt Lake City,- in the county '01. Salt Lake 'and State of Utah, have iii-vented certain 3 same w th a hollow substantially inverted new and useful Improvements in Automatic Dumping .Miuing-Uareand Tipples; and I do hereby declare the following to be a full,

clear, and exact'description otthe' invention, such as; will cnableothers skilled in the art and use the dumping mining cars and tipples', and has for its principal object to provide an appa-- autoinatic in action, both 'to providefor nation over the'hins and withoutthe aid of.

--tion as respectsits strength and dumping dumping the loaded car at the proper destiworkmen to again closethe dumpingdoors of the cars and restore such doorsto locked Another ob ect f the present invention lies in providing a car of.-nnproved construe facilities.

' Ialso providefantolnatic 'dulnpingortripping rneansi for the dumping. doors of the car which will-operate on. the-door releasing: mechan sm carried by the 'car vvhen such car is moved therepast in one direction, but

which tripping means cooperates with further parts on the car to effect the. removal door controlling means when the car is reof the'tripping mans'from the path of the versed in direction.

Referring more particularly to the draw ihg sy 1 designates a car traveling on tho Specification of Letters Patent. Patented Sept. 10; L918 tracks '52 elevated at the point indicated at 3 above the bins into which the material is to be deposited. I p

The car 1 is of any desired construction throughout, except that I prefer to form the Veehaped .false bottom 3 made .to] extend transversely at substantially the center iof the car, and affording the inclined shrfaoes 1'and'5 sloping downwardly toward. the ends 'of the earl, which by virtue Of'.th8ll' shape act in the capacity-of chutes for directing the material through the dumping doors 6 l and i'. The construction and position of the lalse bottom 3 also aids materially in stifi g the car lira-1 M Thegdoors 6 and T as, shownin the chi-- gether with the chutes 4c and 5 the bottom 'of the car. The forward door 7 is held in.

its normally closed position by one-or more. latches 8: two such itches being prefem i as indicated in dotted lines inlFigo, the" same lacing connected together-by a bar 9, and simultaneously proJected and-ret1'acte' d=- into and out of locking position by move} ment imparted:through an arm 10 from a lever 11 pivoted centrally of the car, as 111- 'dica'ted at 12.

I To the opposite side of the lever fulcrum l 12 to that to' which the arm 1 is attached, is coupled a second arm 13 adapted to pro:

ject and retract a pair of latches 14 that slide in guideivays 15' carried beneath the rear door (3, and the ends ofwhich latches are adapted to be received in the lock strikes or sockets 16 carried. by the car body adm cent the rear end. .7 A. bar 17 connects the tvvo latches 1.4, and hinged joints 18 are rnade in euchlatch'rods for the purpose of; permitting the door" 6 toswing down without interference, as shown in Fig. 2. Bothdoors 6 and- 7' are hinged to the car body,'.;- as indicated at 19 and 20, respectively,'-s0

that they may swing down in the same direction'whcn the latches; are released and'mey Y dump the load in thebins 3.

This dumping of the load autonmticatly by exten'dlngthe enus'oft'he car 1', as indicated in Figs. 1 and. 4, Where one of such pro ectmg ends Wlll he n the pathof a trip apparatus.

The trip apparatus 1 lever 11 outwardly heyimd'thc sides of the s composed of long y in Figs. 1 and 2, and on the opposite side ofthetrack to the trip apparatus just de. scribed, is placed a second trip apparatus peter-ably composed of a long lever .30, as socia't'ed witl the short lever 29, the long lever being held upright by the Weights 32 and weights 31 being employed to hold the short lever 29 in the vertical position shown. The doors 6 and 7 carry rollers 35 and 36 disposed in the path of an inclined plane 37 v faced with a metal wear plate 88, whereby such doors are moved from the open to the A closed position, as indicated in Fig. 2.

A platform 39 arranged between the 'traclrrails 2 adjacent the inclined plane 37, and is preferably supported yleldingly by the resilient springs 40. Q A wear plate 41 on this platform 39 has projecting and down- 36 wardly extending end pieces 42 and 43 the latter being in the nature of abridge over which the rollers and 36 may pass from the inclined plane to the platform.

When the rollers and 256 are on the 5 platform -39 the dimming doors 6 and 7 are held. yieldingly in the closed position. The yielding action of the springs serves to compensate for any wear upon the plate 41 l and causes the platform tto he nrged up- Q wardly to hold thedoors tightly closed.

"i The opcsation of the invention is carried on in substantially the following man nert, V (lime, or tillfl'lll of such cars shown at l,

45 aftc being loaded at a point to the-right of the tracks 2 shown in Figs. 1 and 2, are moved to the left from. the loading pointglong suehtracks 2, and as each succeeding cftr passes over that. portion of the track eleeal-e 1 above the hins3 its lumping doors 3 iii id 7 will be released and the load carried rle 'iosited. This dumping action is the resul 401i the projecting end of the lever 11 striking the trip 21', which will cause such lover to be sl'iiftcd from the position shown in Fig. 4 to that shown in Fig. 1. As this shifting ol the lever takcifhidii the latches 8 and 1-iwill. be witlnlrawn froinfthe' nu-ts. they engage, and the doors 'williall by gravity and discharge the load, which will.

be eased in its passage from the mu. by the presence of the chutes st and f. I 1

T After the car p: the dumping point 3 and continues in its progress to the left in 65. Big; 2,, the rollers 36 and 35 on the 'oors back to the passing.

7* and 6 will be caused to encounter and ride up upon the inclined plane 37, 38. Such doors are thereby returned to the closed position where they will be held closed after.

of the lever '11 will strike the trip 30 and will be restored to the original position .shown in Fig. 4, operating at the same time to project the latches 8 and 14 into engagement with their respective parts by which the doors are re-locked. The cars with their doors thus re-lo'cked may pass on to the left until the'last-of the tram. has been dumped and its doors returned to closed and locked position, whereupon the motion of the train may be reversed to lgeing the empty cars original point for the succeeding load.

As the cars return, the rollers 35 and 36 on the doors 6 and 7 will encounter the curved end piece 42,.which will ease their passage over the latform 39 and cause the platform to he sliggitly depressed, this movement bein absorbed by the springs 40.

When the car' approaches from the right, lever 11 comes in contact with lever 21,

which is made in two pieces riveted together so that, when pushed towardthe left, it presses against lever 22, and so'acq'uires the resistance furnished" by the counterweight 2?, which is sufficient to move lever 11 and so withdraw the latches and allbw the doors to open. When the car. approaches the closing trip from the same direction, the Same arrangement operates to close the latches.

When the ear is moved along the track to ward. the right, the pro ection 34, rigidly attached to the car frame, comes in contact with the lever 30, wl'iich', when moved toward the right, is free {tool any connection with the lever 29, and is restrained only by its own conliter-weight 32, whichis only heavy enough to restore lever 30 to a Vertical position again-after the on r has passed. When the car approaches the first, or opening trip from the left, the lever 11' comes directly in contact with the lever 21 which, restrained only by its'own counterweight .24, is readily depressed so as to allow of the car- From the foregoing appreciated that the load is dumped, the dumping doors sphsequently closed and reloclreth'and no disturbancecaused'the loadin g point, all-fsuch operations being done antomatically and without the presence of'laborers' onthe track. s

It is obvious that those skilled in the art may vary the details-of constructionand an rangemi-ul's of parts without departing from llw spirit of my invention, and therefore I do not wish to lie-limited to such features except as may he rcipiired by the claims,
